Notes are only useful when they match your actual course

CramShare started because three students on the same module each spent a weekend writing the same summary, none of them knowing the others were doing it. That is an enormous amount of duplicated work, repeated on every course, every year.

Six things we won’t trade away

Each of these costs us something measurable. They are listed here so you can hold us to them.

  • The course code is the product

    Subject-level matching is why note sites disappoint. A 'psychology summary' is close to useless; a summary for PSY2210 at Utrecht, 2025/26, is worth paying for. Everything we build starts from that tagging.

  • Nobody pays for what they can't see

    Every document opens to a real preview before any money changes hands. It costs us sales on weak documents, which is the point — it is the mechanism that keeps quality up.

  • Sellers get terms in writing

    70%, monthly, no exclusivity, no minimum, no lock-in. Published on the payouts page rather than buried in a contract, and any change to it will be announced before it takes effect.

  • Free has to actually be free

    The community library is not a trial. It has no page limits, no watermarks and no daily cap. Plenty of students never pay us anything, and the model works anyway.

  • We say no to material that isn't the seller's

    Lecture slides, textbook scans and other students' work get rejected in review. It costs us inventory. It also keeps sellers, buyers and universities out of trouble.

  • Ranking can't be bought

    Documents rank on how often they are re-opened before an exam. There is no promoted placement and no way to pay for position, because the moment there is, results stop being useful.

How it got here

Four months from the first conversation to opening the catalogue.

  1. June 2026

    Concept research. Working out what a notes marketplace actually gets wrong, and whether matching on the course code rather than the subject was worth building a product around.

  2. July 2026

    UI design. Every screen drawn before any of it was built, including the ones nobody enjoys designing — refund, rejection, takedown.

  3. August 2026

    Technical implementation. Catalogue and search, uploads and review, payouts, reports and takedowns.

  4. September 2026

    Launch. The catalogue opens with the preview rule, the review queue and the takedown process already in place, rather than added after the first complaint.

How we make money

We take 30% of each premium sale. That is the entire business model. There is no advertising, no data sold to third parties, no paid placement in search results and no subscription that quietly renews.

The free library is funded by the premium side. It is not a loss-leader we plan to close later — free documents are what make the catalogue worth searching, and a student who never pays us anything is still the reason the next one finds what they need.

If that ever changes, it will be announced on this page before it happens, not discovered in a terms update.

Two ways in.

Search the free library without an account, or publish the notes you already wrote and start earning.
